Abstract
A pair of compasses comprises two adjustable angles and a handle to articulate the two angles, is characterized in that a semicircular dial gauge is fixed on one compass angle, the other compass angle is provided with a knob to fix the compass angle on the semicircular dial gauge. The semicircular dial gauge has two rows of different calibrations, one is metric system calibrations, and the other is Chinese system calibrations. With simple structure and convenient usage, the utility model can conveniently draw a circle with a certain diameter or radius.
Description
Technical field
The utility model relates to the stationery technical field, concrete relates to a kind of compasses.
Background technology
Present compasses, when drawing circle, need measure out two jiaos length with a yardstick, could draw circle as radius then, and in drawing the circle process, compasses change for two jiaos easily, cause drawn radius of a circle inaccurate, perhaps two angular distances of compasses change in the process of drawing, the basic picture circle that do not come out.
The utility model content
Technical problem to be solved in the utility model is, a kind of compasses are provided
In order to address the above problem, the technical solution of the utility model is such:
A kind of compasses comprise two jiaos of adjustable angle, and with two jiaos of hinged handles, it is characterized in that, are set with half circular scale table on one jiao of described compasses, and another angle of compasses has the compasses angle is fixed on knob on the semicircle graduation apparatus.
Described semicircle graduation apparatus has the different scale of two rows, row's metric system scale, and a row is city's scale making.
Beneficial effect, the utility model is simple in structure, and is easy to use, the circle of can draw very easily certain diameter or radius.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of a kind of compasses of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of compasses comprise two jiao 1,2 of adjustable angle, and with two jiaos of hinged handles 3, are set with half circular scale table 4 on one jiao 1 of described compasses, and another angle 2 of compasses has compasses angle 2 is fixed on knob 5 on the semicircle graduation apparatus 4.
Described semicircle graduation apparatus 4 has the different scale of two rows, row's metric system scale, and a row is city's scale making.
Beneficial effect, the utility model is simple in structure, and is easy to use, the circle of can draw very easily certain diameter or radius.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
